Particles in Harmony 14

For a school animation 2D short, I have to make an icescream cones rain. I tried using the rain splash particle exemple of Harmony but I don’t understand how to set the splash exactly when the particle hit the planar region with a bounce node. Somehow I think it is possible since it does just that in the rain splash exemple.

Here’s my temporary sketch for the particle test.
